#
# By default, we define the source directory for libraries to be
# one level up from the ISA-specific directory, where the code is
# actually built.  Many libraries define a 'common' directory to
# contain the source.  These libraries must redefine SRCDIR as:
#	SRCDIR = ../common
# Other variations are possible (../port, ../src, etc).
#
SRCDIR =	..

#
# We define MAPFILES here for the benefit of most libraries, those that
# follow the convention of having source files and other common files
# in the $(SRCDIR) directory.  Libraries that do not follow this
# convention must define MAPFILES, or MAPFILEDIR for themselves.
# Libraries that do follow this convention but that need supplemental
# ISA-specific mapfiles can augment MAPFILES like this:
#	MAPFILES += mapfile-vers
#
MAPFILEDIR =	$(SRCDIR)
MAPFILES =	$(MAPFILEDIR)/mapfile-vers

#
# If HDRDIR is left unset, then it's possible for the $(ROOTHDRDIR)/%
# install rule in lib/Makefile.targ to generate false matches if there
# are any common directory names between / and /usr/include (`xfn' is
# one common example).  To prevent this, we set HDRDIR to a directory
# name that will almost surely not exist on the build machine.

#
# We don't build archive (*.a) libraries by default anymore.
# If a component of the build needs to build an archive library
# for its own internal purposes, it can define LIBS for itself
# after including Makefile.lib, like this:
#	LIBS = $(LIBRARY)
# or:
#	LIBS = $(LIBRARYCCC)
# Archive libraries must not be installed in the proto area.
